What Does Recent Neuroscience Tell Us About Criminal Responsibility?, Uri Maoz, Gideon Yaffe

Psychology Faculty Articles and Research

A defendant is criminally responsible for his action only if he is shown to have engaged in a guilty act—actus reus (eg for larceny, voluntarily taking someone else’s property without permission)—while possessing a guilty mind—mens rea (eg knowing that he had taken someone else’s property without permission, intending not to return it)—and lacking affirmative defenses (eg the insanity defense or self-defense). We therefore first review neuroscientific studies that bear on the nature of voluntary action, and so could, potentially, tell us something of importance about the actus reus of crimes.Then we look at studies of intention, perception of …

Proper Orthogonal Decomposition Methods For The Analysis Of Real-Time Data: Exploring Peak Clustering In A Secondhand Smoke Exposure Intervention, Vincent Berardi, R. Carretero-González, N. E. Klepeis, A. Palacios, J. Belletierre, S. Hughes, S. Obayashi, M. F. Hovell

Psychology Faculty Articles and Research

This work explores a method for classifying peaks appearing within a data-intensive time-series. We summarize a case study from a clinical trial aimed at reducing secondhand smoke exposure via the installation of air particle monitors in households. Proper orthogonal decomposition (POD) in conjunction with a k-means clustering algorithm assigns each data peak to one of two clusters. Aversive feedback from the monitors increased the proportion of short-duration, attenuated peaks from 38.8% to 96.6%. For each cluster, a distribution of parameters from a physics-based model of airborne particles is estimated. Peaks generated from these distributions are correctly identified by POD/clustering …

Intra-Individual Consistency In Endocrine Profiles Across Successive Pregnancies, Molly Fox, Curt A. Sandman, Elyssia Poggi Davis, Laura M. Glynn

Psychology Faculty Articles and Research

Context: It is yet unknown how similar women’s hormone levels are during successive pregnancies, and very little is known about the degree to which siblings experience similar prenatal environments. Given the importance of understanding how women’s reproductive life-histories exert cumulative effects on health via hormone exposure, and the importance of understanding how fetal programming via endocrine signaling affects sibling trait concordance, here we address this important lacuna in the literature.

Objective: To investigate how consistent are women’s hormone profiles across two successive pregnancies.

Design and Main Outcome Measures: This longitudinal, prospective study followed a cohort of 28 …

Relationships Between Positive Psychological Constructs And Health Outcomes In Patients With Cardiovascular Disease: A Systematic Review, Christina M. Dubois, Oriana Vesga Lopez, Eleanor E. Beale, Brian C. Healy, Julia K. Boehm, Jeff C. Huffman

Psychology Faculty Articles and Research

Depression and anxiety are well-known to be associated with adverse health outcomes in cardiac patients. However, there has been less work synthesizing the effects of positive psychological constructs (e.g., optimism) on health-related outcomes in cardiac patients. We completed a systematic review of prospective observational studies using established guidelines. A search of PubMed and PsycINFO databases from inception to January 2014 was used to identify articles. To be eligible, studies were required to assess effects of a positive psychological construct on subsequent health-related outcomes (including mortality, rehospitalizations, self-reported health status) in patients with established heart disease. Exploratory random effects' meta-analyses were …

Visual Feedback Dominates The Sense Of Agency For Brain-Machine Actions, Nathan Evans, Steven Gale, Aaron Schurger, Olaf Blanke

Psychology Faculty Articles and Research

Recent advances in neuroscience and engineering have led to the development of technologies that permit the control of external devices through real-time decoding of brain activity (brain-machine interfaces; BMI). Though the feeling of controlling bodily movements (sense of agency; SOA) has been well studied and a number of well-defined sensorimotor and cognitive mechanisms have been put forth, very little is known about the SOA for BMI-actions. Using an on-line BMI, and verifying that our subjects achieved a reasonable level of control, we sought to describe the SOA for BMI-mediated actions. Our results demonstrate that discrepancies between decoded neural activity and …

Variability Modifies Life Satisfaction's Association With Mortality Risk In Older Adults, Julia K. Boehm, Ashley Winning, Suzanne Segerstrom, Laura D. Kubzansky

Psychology Faculty Articles and Research

Greater life satisfaction is associated with greater longevity, but its variability across time has not been examined relative to longevity. We investigated whether mean life satisfaction across time, variability in life satisfaction across time, and their interaction were associated with mortality over 9 years of follow-up. Participants were 4,458 Australians initially at least 50 years old. During the follow-up, 546 people died. After we adjusted for age, greater mean life satisfaction was associated with a reduction in mortality risk, and greater variability in life satisfaction was associated with an increase in mortality risk. These findings were qualified by a significant …

Fatalism, Diabetes Management Outcomes, And The Role Of Religiosity, Vincent Berardi, John Bellettiere, Orit Nativ, Slezak Ladislav, Melbourne Hovell, Orna Baron-Epel

Psychology Faculty Articles and Research

This study aimed to determine whether fatalistic beliefs were associated with elevated levels of glycated hemoglobin (HbA1c) and to establish the role of religiosity in this relationship. A cross-sectional survey was conducted on a sample of 183 Jewish adults with diabetes visiting a large medical center in northern Israel. Self-administered questionnaires assessed level of religiosity, fatalistic beliefs, diabetes management behaviors, and demographic/personal characteristics; laboratory tests were used to measure HbA1c. Multivariate regression indicated that fatalism was significantly associated with HbA1c (β = 0.51, p = 0.01). The association was no longer statistically significant after including self-reported religiosity in the …

Revisiting A Common Measure Of Child Postoperative Recovery: Development Of The Post Hospitalization Behavior Questionnaire For Ambulatory Surgery (Phbq-As), Brooke N. Jenkins, Zeev N. Kain, Sherrie H. Kaplan, Robert S. Stevenson, Linda C. Mayes, Josue Guadarrama, Michelle A. Fortier

Psychology Faculty Articles and Research

Background

The Post Hospitalization Behavior Questionnaire (PHBQ) was designed for assessing children's posthospitalization and postoperative new‐onset behavioral changes. However, the psychometric properties of the scale have not been re‐evaluated in the past five decades despite substantial changes in the practice of surgery and anesthesia. In this investigation, we examined the psychometric properties of the PHBQ to potentially increase the efficacy and relevance of the instrument in current perioperative settings.

Method

This study used principal components analysis, a panel of experts, Cronbach's alpha, and correlations to examine the current subscale structure of the PHBQ and eliminate items to create the Post …

Paradoxical Interaction Between Ocular Activity, Perception, And Decision Confidence At The Threshold Of Vision, Aaron Schurger

Psychology Faculty Articles and Research

In humans and some other species perceptual decision-making is complemented by the ability to make confidence judgements about the certainty of sensory evidence. While both forms of decision process have been studied empirically, the precise relationship between them remains poorly understood. We performed an experiment that combined a perceptual decision-making task (identifying the category of a faint visual stimulus) with a confidence-judgement task (wagering on the accuracy of each perceptual decision). The visual stimulation paradigm required steady fixation, so we used eye-tracking to control for stray eye movements. Our data analyses revealed an unexpected and counterintuitive interaction between the steadiness …

The Prospective Association Between Positive Psychological Well-Being And Diabetes, Julia K. Boehm, Claudia Trudel-Fitzgerald, Mika Kivimaki, Laura D. Kubzansky

Psychology Faculty Articles and Research

Objective: Positive psychological well-being has protective associations with cardiovascular outcomes, but no studies have considered its association with diabetes. This study investigated links between well-being and incident diabetes.

Methods: At study baseline (1991-1994), 7,800 middle-aged British men and women without diabetes indicated their life satisfaction, emotional vitality, and optimism. Diabetes status was determined by self-reported physician diagnosis and oral glucose tolerance test (screen detection) at baseline and through 2002-2004. Incident diabetes was defined by physician-diagnosed and screen-detected cases combined and separately. Logistic regression estimated the odds of developing diabetes controlling for relevant covariates (e.g., demographics, depressive symptoms). Models …

Life Balance – A Mindfulness-Based Mental Health Promotion Program: Conceptualization, Implementation, Compliance And User Satisfaction In A Field Setting, Lisa Lyssenko, Gerhard Müller, Nikolaus Kleindienst, Christian Schmal, Mathias Berger, Georg Eifert, Alexander Kölle, Siegmar Nesch, Jutta Ommer-Hohl, Michael Wenner, Martin Bohus

Psychology Faculty Articles and Research

Background

Mental health disorders account for a large percentage of the total burden of illness and constitute a major economic challenge in industrialized countries. Several prevention programs targeted at high-risk or sub-clinical populations have been shown to decrease risk, to increase quality of life, and to be cost-efficient. However, there is a paucity of primary preventive programs aimed at the general adult population. “Life Balance” is a program that employs strategies borrowed from well-established psychotherapeutic approaches, and has been made available to the public in one federal German state by a large health care insurance company. The data presented here …
